The traditional answer is "Practice!" And daisy_knotwise and I have just gone over the two songs that we'll be performing at the Pegasus Concert tomorrow night at OVFF, Marcon Ballroom and Our Space Opera Goes Rolling Along. I've also typed up a set of words with the chords (and where to put the silly capo), because it really doesn't pay to forget the words and chords to someone else's song, even if you do believe you have it in eidetic memory.
The car is packed. The songs are printed. We can go to bed now. Yay!
(Oh, and we have four microphones for jslove. And a copy of the scratch tracks and lyric sheets for Falling Toward Orion for the Interfilk auction.)
